| titleOfInvention | Mixture for modifying and alloying cast iron |
| abstract | The invention relates to the field of metallurgy and can be used to modify cast iron for the manufacture of thin-walled castings. The purpose of the invention is to dispose of the waste, eliminate edge chill and increase the duration of the preservation of the modifying effect. Prepare a modifying mixture of the following composition, May. %: carbon. 5-10; waste of alumina boron-containing fiber 8-12, 'ferrosilicon remains 1 ^. The melt is cast iron and its modification is carried out at 1400-1420 ° gf. C. The application of the proposed modifier makes it possible to utilize the yields of aluminum-boron-containing fiber, eliminate edge chill and increase the duration of the modifying effect. Table 1. The invention relates to foundry, in particular, to modifier compositions for modifying gray iron, and can be used to make responsible thin-walled castings in mechanical engineering. The aim of the invention is to eliminate chamfer in castings, to increase the duration of preservation of the modifying effect and to reduce the cost of modifying! ** "turing while maintaining high strength properties. The goal is achieved by the fact that the mixture for modifying and alloying cast iron contains carbon, ferrosilicon FS75 and aluminum bullet waste and fiber in the following ratio of infectious substances, wt%; Carbon 5-10 Aluminous borsilicate fiber waste 8-12 Ferrosilicon Other Carbon in the mixture performs two functions: it serves as natural nuclei during the crystallization of the alloy and is a reducing agent for boron and aluminorderous debris and it is also used as a silver reducing agent and it is a good combination with its own body, and the aluminacers will first put on their own and they are boron-alumina and they are boron and aluminacers are already in offspring; carbon content is selected based on the most complete boron reduction conditions. The lower limit of carbon content |
